Security isn't as much of an issue on a power-line network as it is on a Wi-Fi network. After all, there's no data flying through the air to be intercepted. Still, you should take precautions, especially if you live in a multi-unit building. For one thing, you can change your network's name from the default name that Netgear provides. Any adapter (and client) that attempts to join the network will have to know its name. You can also set a password on your network to keep out would-be intruders.
In our Labs' tests, the Netgear Powerline HD Ethernet Adapters clocked an impressive 52.7Mbps throughput rate--faster than that of the Panasonic adapters, which posted a 35.4Mbps rate. While 52.7Mbps is well off the theoretical maximum of 200Mbps, it's still more than enough for standard home-use tasks, such as Web surfing. And according to CNET's home video experts, this rate will more than suffice for transmitting high-def content.
Netgear backs the Powerline HD Ethernet Adapters with a one-year warranty. Toll-free phone support for basic setup issues is free for the first 90 days. More-detailed assistance can be had for a price: a hefty $32.95 per incident (up to 30 minutes). If that seems steep, start with Netgear's site, which has FAQs, a troubleshooter, and downloadable installation and user guides. The included CD has a user guide for reference, too.
